ABSTRACT
BACKGROUND: Sézary syndrome (SS) is an aggressive type of cutaneous T-cell lymphomas (CTCL). Due to its low prevalence, there are limited data on real-world treatment patterns of available SS therapies. Furthermore, recent approvals of new agents for patients with CTCL as well as COVID-19 likely impacted real-world treatment patterns. OBJECTIVE: To examine real-world treatment patterns and the impact of COVID-19 among SS patients treated in 2018-2020 in the United States. METHODS: Patients in the 2018-2020 Symphony Health Solutions database were classified into 3 groups: ≥1 diagnosis of SS (ICD-10-CM code: C84.1x) in 2018, 2019, and 2020, respectively. Patient characteristics and treatment patterns for National Comprehensive Cancer Network guideline 2.2021 recommended therapies were examined: systemic therapy (e.g., extracorporeal photopheresis (ECP), parenteral, oral agents), skin-directed therapy (SDT, e.g., topical, local radiation, total skin electron beam therapy, phototherapy) and bone marrow transplant. The impact of COVID-19 was assessed using quarterly analysis. RESULTS: The analyses included 869, 882, and 853 SS patients in 2018, 2019, and 2020, respectively (mean age: 66.3, 66.9 and 67.3 years; male: 54.4%, 54.8%, and 55.6%). Overall, systemic therapy increased from 2018-2020 (41.8% to 46.5%), with increased parenteral (20.7% to 28.7%) but decreased ECP (17.0% to 13.5%) usage. SDT increased from 2018-2020 (48.9% to 52.9%), with increased topical (42.3% to 48.3%) but decreased phototherapy (6.3% to 4.1%) usage. ECP, mogamulizumab, and bexarotene were the most prescribed systemic therapies in 2019-2020, with mogamulizumab being the only one with increased usage over time. Quarterly analysis showed decreasing ECP from Q1 to Q4 within each year, with a notable drop in Q2 2020. For parental systemics, there was an increasing trend in 2019 and 2020, but lower utilization in Q4 2020 than in Q3 2020. For oral systemic, there was a notable drop in Q2 2020 but an increased trend in Q3-Q4 2020. CONCLUSIONS: This claims analysis indicated increased use in systemic and SDT among SS patients in 2018-2020. The quarterly analysis indicated that the drop in ECP and oral systemic usage in Q2 2020 coincided with the onset of the pandemic, but there was a stable use of parenteral systemic during 2020.

BACKGROUND: Bronchiolitis obliterans syndrome (BOS) is the main limitation to long-term survival following lung transplantation. Several studies generated promising results regarding the efficacy of extracorporeal photopheresis (ECP) in BOS management. We aimed to compare FEV1 evolution in ECP-treated versus non-ECP treated patients among BOS recipients. METHODS: Overall, 25 BOS patients were included after receiving optimized treatment. Data were collected retrospectively. Twelve patients with moderate and refractory BOS received ECP treatment. RESULTS: Among non-ECP treated control patients (n = 13), six experienced persistent decline without undergoing ECP for various reasons. ECP stabilized pre-ECP lung function during the subsequent 6 to 24 months (repeated measures one-way Anova, p = 0.002), without any significant impact observed by either FEV1 decline speed prior to ECP or time between BOS diagnosis and ECP onset. ECP-treated patients displayed a similar risk of an additional permanent 20% or higher drop in FEV1 after BOS onset compared to controls, but a lower risk compared to control decliners (p = 0.05). ECP quickly stabilized FEV1 decline in refractory BOS patients compared to non-treated decliners. CONCLUSIONS: We confirmed that this therapeutic option against refractory BOS can be managed in a medium-size LTx center, with a satisfactory efficacy and an acceptable tolerance.

Ultraviolet blood irradiation (UBI) was used with success in the 1930s and 1940s for a variety of diseases. Despite the success, the lack of understanding of the detailed mechanisms of actions, and the achievements of antibiotics, phased off the use of UBI from the 1950s. The emergence of novel viral infections, from HIV/AIDS to Ebola, from SARS and MERS, and SARS-CoV-2, bring back the attention to this therapeutical opportunity. UBI has a complex virucidal activity, mostly acting on the immune system response. It has effects on lymphocytes (T-cells and B-cells), macrophages, monocytes, dendritic cells, low-density lipoprotein (LDL), and lipids. The Knott technique was applied for bacterial infections such as tuberculosis to viral infections such as hepatitis or influenza. The more complex extracorporeal photopheresis (ECP) is also being applied to hematological cancers such as T-cell lymphomas. Further studies of UBI may help to create a useful device that may find applications for novel viruses that are resistant to known antivirals or vaccines, or also bacteria that are resistant to known antibiotics.

Psoriasis is a chronic inflammatory skin disease that is characterized by well-demarcated erythematous plaques with a silver scale. Although many new and emerging therapeutic agents are often sufficient to control the disease, there is still a need for alternative treatment options in challenging cases. Extracorporeal photopheresis (ECP) has been applied to many T-cell-mediated diseases to restore immune homeostasis and treat psoriasis effectively. In this paper, we present a psoriasis patient who did not respond to methotrexate, narrowband ultraviolet B, or acitretin. Because of a diagnosis of non-Hodgkin lymphoma, the patient had contraindications for cyclosporine, fumaric acid esters, and biologics but achieved remission with a total of 12 sessions of ECP in two and a half months. Although exacerbation was recorded after polymerase chain reaction (PCR) confirmed coronavirus 2019 (COVID-19) disease infection at the end of the first month, scores from the psoriasis area severity index (PASI) and dermatological life quality index (DLQI) were regressed significantly within two and a half months. ECP seems to provide an effective and rapid response for psoriasis and should be considered for psoriasis patients who fail to respond or have contraindications to existing treatments.
